2001 CHEVROLET LUMINA

My 2001 Chevy Lumina is overheating, recently I changed the thermostat and flushed out the radiator. So over the two weeks the temperature on the car would heat up a little bit, the car would blow out cool air, then the temperature of the engine would drop down dramatically and it would blow hot air back out. Did I buy a faulty thermostat by chance or was that signs of my pump for the coolant system going out? Currently the car is back to overheating rapidly again and the low coolant light comes on. After flushing the radiator I found out its a 3gallon system and ive only been able to put 2.5gallongs back in. Could the flush I used not have gotten rid of all the gunk in the radiator so I just need to get it steemed?

Top it off and bleed the air out to the system. There may be a valve at the top the the water outlet to do this. Also observe your fan to see if it is in sync with the thermostat or at all. If you dont get enough hot coolant thru the heater core the air will be cold. I dont think a half of a gallon would be a big difference though. A stat is cheap so id change it for giggles
